High-density polyethylene degradation into low molecular weight gases at 1823 K: An atomistic simulation
L Ramin and MHN Assadi and V Sahajwalla, JOURNAL OF ANALYTICAL AND APPLIED PYROLYSIS, 110, 318-321 (2014).
Using molecular dynamics simulation, we present a comprehensive study of the volatile thermal degradation of high-density polyethylene (HDPE) across a temperature range of 300 K to 1823 K. We find that degradation at temperatures higher than similar to 1373 K generates significant quantities of reducing gases such as CHn and hydrogen molecules which are beneficial to the steelmaking industry. Our results provide a new understanding of HDPE's phase transformation from solid to gas that occurs during superheating at steelmaking's electric arc furnace environment offering a new method for eliminating end-of-life HDPE from landfill.
